How to Winterize Your Plumbing System
When temperatures drop, your plumbing system becomes vulnerable to serious damage, especially from frozen or burst pipes. Knowing How To Winterize Plumbing can save you thousands in repairs and ensure your home is prepared for the cold season.
At Eastside Repipe Plumbing, we help homeowners across Washington protect their homes with smart, seasonal maintenance strategies. Whether you live in a newer build or an older property, taking proactive steps for Plumbing Prep For Cold Weather is essential to prevent emergencies.
Step 1: Inspect and Drain Outdoor Plumbing
Outdoor spigots, hoses, and irrigation lines are often the first to freeze. Begin your Plumbing Prep For Cold Weather by:
Disconnecting all hoses
Shutting off water to outdoor faucets
Draining sprinkler systems and external pipes
If your home has a dedicated shut-off valve for outdoor plumbing, turn it off and let any remaining water drain out.
Step 2: Insulate Pipes in Vulnerable Areas
Insulating exposed pipes in unheated spaces like basements, attics, garages, and crawl spaces is one of the best ways to Prevent Frozen Pipes. Use foam pipe sleeves, heat tape, or fiberglass insulation.
Pipes that are near exterior walls or under cabinets are also at risk. Open cabinet doors to allow warm air to circulate and keep your thermostat steady, even when you're away.
For professional insulation and repiping solutions, consider Eastside Repipe Plumbing’s Repiping Services for added peace of mind.
Step 3: Seal Cracks and Gaps Around Pipes
Check for drafts or gaps where plumbing enters the home. Use caulk or expanding foam to seal holes in the foundation, walls, or floors. Blocking cold air infiltration is a crucial step in How To Winterize Plumbing and protects your pipes from rapid temperature drops.
Step 4: Drain and Flush Your Water Heater
As part of your winter maintenance, drain a few gallons from your water heater to remove sediment. This helps it run more efficiently and ensures you have reliable hot water throughout winter.
If your water heater is older or underperforming, consult the team at Eastside Repipe Plumbing to discuss repairs or replacements.
Step 5: Know Where Your Shut-Off Valve Is
In case of a burst pipe, knowing how to quickly shut off your water can minimize damage. Make sure everyone in your household knows the location of the main shut-off valve and how to operate it.
For long trips, you may even want to shut off your water supply entirely and drain the system to avoid unexpected issues.
Step 6: Let Faucets Drip During Extreme Cold
If temperatures are expected to fall well below freezing, let cold-water faucets drip slowly—especially in areas with poor insulation. Moving water is less likely to freeze and helps you Prevent Frozen Pipes in key sections of your plumbing.
Step 7: Schedule a Professional Winter Plumbing Inspection
Even with DIY prep, a licensed plumber can identify hidden vulnerabilities in your system. Eastside Repipe Plumbing offers seasonal inspections and maintenance to ensure your home is ready for harsh winter conditions.
